Established in 2013, the Office of Sustainability was created to direct and enhance all of the College's campus and community based sustainability goals and priorities. The mission of the Office of Sustainability is to advance the understanding and application of holistic sustainability through curricular integration and by helping the College serve as a model of holistic sustainability. At Connecticut College, sustainability is a framework by which long-lasting solutions to local and global challenges are developed through understanding the connections among social equity, environmental stewardship, and economic well-being and including all three within all decision-making and strategic planning processes. The office's mission is deeply embedded in the College's values and mission to prepare students to act as citizens in a global society.

The College and the Office of Sustainability specifically focuses on the follow sustainability priorities:

Support and engage with existing efforts across campus to diversify the college, to collaborate with the surrounding community and to reduce the college’s impact on the environment

Increase the educational opportunities such as courses, events, etc., that are related to sustainability

Develop and expand projects and programs that minimize costs and maximize revenue by promoting environmental stewardship and social equity

Consider the tenets of holistic sustainability equally when making decisions to support the long-term success and viability of the College
